The analysis of modern radar signals parameters in Electronic Intelligence system

Electronic Intelligence (ELINT) is the result of observing the signals transmitted by radars to obtain information about their capabilities and applications. The paper describes the role of specific radar parameters, mainly the different types of inter-pulse modulation and in which way they may be applied in the electronic intelligence system. A few examples of measured signals parameters belonging to radars with different applications are illustrated. At the end of this paper the knowledge base approach to radar signal recognition was presented.
